CAR-HEATING APPAI QATUS.

SPECIFICATION forming part of Letters Patent No. 434,022, dated. August12, 1890.

Application filed May 18, 1889.

To all whom it may concern.-

Be it known that we, DANIEL F. LAPAUGH and LOUIS T. LAPAUGH, of Utica,county of paratus, of which the following is a specifica tion, referencebeing had to the accompanying drawings, in which' Figure l is a planview of the bottom of the car inside. Fig. 2 is a perspective of theinterior of the car-body. Fig. 3 is a like view looking into the end.Fig. 4 is an enlarged frontelevation of the heater detached. Fig. 5 is aside elevation of the same.

This invention relates to devices and mechanisms for heating,railway-ears with hot air, the apparatusbeing independent of thelocomotive, so that it will heat a train when the locomotive isdetached.

The object of our invention is to produce a means for heatingrailway-cars with hot air, which will heat the largest quantity of airwith a minimum quantity of fuel, and which will be safe in case of awreck and not liable to burn up, the fire being inclosed beyond allprobable chance of escape.

Our invention consists in the several novel features of construction andoperation hereinafter described, and which are specifically set forth inthe claim annexed.

At a suitable point within the car A, preferably central, we mount orset up our heater B. .This heater consists of an outer shell comprisingthe combustion-chamber, a grate adjacent to the bottom, and a chute orchutes 2, opening into the fire-pot contiguous to the grate.

tially the bottom of the heater, where the lower end of eachheating-pipe is connected to tubing 4:, which carries the heated airfrom the heater to the cars.

The floor of the car for a part of its distance or width is providedwith an air-chamber 5 below the bottom proper, and 6 is a port at eachend of the car for admitting fresh air into this chamber, and each portis provided with a slide or other damper for closing the same wholly orpartially. The lower ends of the heating-pipes 0 open into this chamber5, as shown at 7, and receive fresh air from this chamber. A portion ofthe bottom of this car is also elevated and covered with a removablegrating 8, by the removal of which the pipes 4 can readily be reached,examined, or repaired, if necessary.

At 0 we show coal-bunkers for the storage of fuel.

WVhat we claim is- A car-heating apparatus consisting of a carconstructed of iron and provided with an airchamber 5, and means foradmitting air thereto, and a piping-slot covered with a re movablegrating, a heater mounted in said car, consisting of a body providedwith a grate and air-heating pipes having one end connected to theair-chamber 5, and thence wound upward and sinuously around the body toits top, and thence downward to the dischargepipe, to which it isconnected,and dischargepipes leading from the heater to the other carsof the train, substantially as described.

In witness whereof we have hereunto set our hands this 11th day of May,1889.
